Do not suddenly push the lifting handle to the "down position" in the middle of a full-load lifting
If this operation error occurs, the car suddenly rushes down, which will bring a great impact to the frame, and even an accident may occur. Therefore, the above operations should be avoided as much as possible. If there are special circumstances, they must also be operated carefully, and the landing speed must be slowed down as much as possible, and the carriage must not be suddenly dropped to the bottom.
